Abstract

A fluorescent gas measurement device is provided for measuring an air parameter at a remote sample location (12). The device comprises means (32, 32", 32" ', 182) for inducing at least one molecular species within the air at the sample location to emit fluorescence, means (42, 42", 42"") for measuring the intensity of said fluorescence, and means (22) responsive to the measured fluorescence intensity for computing the desired parameter. The device is adapted to measure a parameter related to the concentration of said molecular species in the air, such as density, pressure and/or barometric altitude. The device may be installed aboard an aircraft.
